Facade sealing across Melvich

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Our process

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For work around Melvich, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions
  • Have the specification and drawings to hand

Facade sealing in Melvich

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. We work on stone and brick facade joints, shopfront frames and window and door perimeters, and what we’re called in for most is cold air coming in at window perimeters and leaks at window and door perimeters. One point of contact handles commercial sealant work in Melvich from the first photographs to the final walk-round, for single jobs and planned programmes alike.

In smaller places such as Melvich, building work tends to be single schemes rather than big developments. Exposed elevations in Scotland put facade and perimeter joints to work from day one, so the sealant choice matters.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Should maintenance staff do it?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Melvich: questions and answers

Does a coastal location like Melvich affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is Melvich too small for you to travel to?

Not at all. Melvich is within our area. We work across every Scottish council area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

New build and refits around Melvich

Melvich is within about 1 mile of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Melvich is on Scotland’s drier eastern side. Winter mornings can still bring frost and condensation on steel and glass. We agree external dates with the site team and keep internal work ready.

Hotel extensions and refits, at places such as Melvich Hotel, less than half a mile north-west of Melvich, usually run between busy periods, so the sealing is squeezed into short windows.

Melvich (Gaelic: Meabhaich) is about 15 miles west of Thurso, in Highland. We cover commercial sites throughout Melvich, for single jobs and planned programmes alike. Melvich is one of 256 places we cover in Highland.

Work on facade joints is covered throughout KW14, for business premises of every kind. Among the streets we cover are Melvich Terrace and Pentland Terrace. Nearby places we also cover include Portskerra (1 mile north-west), Strathy (3 miles west), Reay (5 miles east), Forss (11 miles east) and Am Blàran Odhar (11 miles west). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

Why act early in Melvich

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Renewing every failing joint on one visit is the sensible approach for a place like Melvich. Send photos and we’ll quote for everything together.

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Joints too narrow for the movement they take, which need redesign
  • Replacing glass or failed glazing units
  • Damaged frames that need replacing

If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

Where we work in Melvich

  • Perimeter joints where frames meet the structure
  • Shopfront frames
  • Cladding panel joints
  • Stone and brick facade joints
  • Coping and flashing joints
  • Window and door perimeters

When to call us in Melvich

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.

Common reasons buildings call us in:

  • Failed seals around shopfront and entrance frames
  • Facade joints cracked through the middle
  • Leaks at window and door perimeters
  • Cladding panel joints that have opened up

For contractors building in or near Melvich, we seal to the drawings, the specification and the programme.

Questions to ask before you appoint anyone

How the job changes by surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone.

Precast concrete panels

Joints between precast panels carry real movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.
